Specification of Letters Patent.

Application filed January 16, 1914. Serial No. 812,601.

providing drop curtains or barriers at various points of the train as for instance; at the entrance of the engine cab or on the platform of the cars in the train. These I arrange to drop automatically when anybody should step on the platforms of the various-cars or engine. When the intruder steps on the platform, a portion of the same is depressed, this completes an electric circuit which operates mechanism to release one or more of the said curtains or barriers. The intruder is then prevented from entering the car or cab, as the case may be. When desired several of these curtains may be employed, so as to inclose the said person and prevent his escape.

I have illustrated the invention in the accompanying drawings, in which;

Figure 1 is a side view of the engine, and car in which is employed my improvement. Fig. 2 is an enlarged side view of a portion of acar to which the said device is attached. Fig. 3 is a horizontal section of the car. Fig. 4c is a rear view of locomotive cab with a portion of the tender in cross section; showing the said device applied to the cab. Fig. 5 is a similar view, showing the drop curtain released. Fig. 6 is a sectional elevation of the boX, which holds the folding curtain. Fig. 7 is a sectional detail of a curtain in its released position. Fig. 8 is a section taken on the line m-m of Fig. 6. Fig. 9 is a diagrammatic view, of the car platform;

"showing the curtain and means for operating the latter, the said curtain being shown in its folded position. Fig. 10 is a diagrammatic view, showing the curtain in its down position. Fig. 11 is a modification of the circuit closer. Fig. 12 is a modification of the curtain and its retaining device.

In the drawings 1 refers to the curtain, which is preferably constructed of a series of articulated strips 2, the same being hinged at 3. The bottom of the curtain consists of a heavy strip or weight 4. The said curtain may be attached by means of screws 5 t0 the top piece 6; the whole being inclosed in a box 7 8-8 are latches, which have proj each of the said latches being pivoted at 10 in the box 7 or to a suitable support. Each latch 8 has a cross piece or armature 11.

12 is a magnet, having a core 13, wires 14: and 15 leading from the said magnet to a battery 16, and a circuit closer 17 The said circuit closer has contact points 19 and 20. The circuit closer 17 may be on the platform 21 of a car, or on the engine. When a person steps on the circuitcloser, this will close the circuit, and operate the latches 8-8. The curtain will then drop and form a barrier which will prevent the person from entering the car or cab of the engine, as the case may be.

As shown in Fig. 3 several of the circuit closers may be employed on several points, on the platform; this with the aid of several other. It will also, if desired, inclose the person and thus hold him on the platform until taken into custody.

In Fig. 11 I have shown a modification of the circuit closer, which consists of a hinged foot piece 17*, which may be placed on the engine, so that when a person steps on the same, it will operate the curtain or barrier, and thus prevent the said person from entering the cab.

In Fig. 12 I have shown a modification of the curtain 2 the same being rolled up, instead of being folded up, the same being on a roller 30, which has a ratchet 31, and is held by a pawl 32. This is operated by a magnet 12*, and a circuit closer, similar to the one described in the preceding description. i

In Figs. 9 andlO, I have shown means for manually closing the' circuit which con- 12, and a cut-out switch 13. In these figures,

ections 9,:

curtains will prevent the person from entering the car or proceedlng from one into the two oppositely-disposed gravity dogs 40 are also shown adapted to engage over the weighted bar 4 to secure the lower end of the curtain.

It will thus be seen that my invention provides a very useful device, for the purposes specified.

What I claim is 1. The combination with a car platform, of a resiliently-supported treadle device serving as a circuit-closer, electrical contacts below said treadle-deirice, an-electric ,ity-drop curtain above circuit Which includes said contacts, agravsaid plattorm, a pivoted catch adapted to engage said curtain and carrying an armature, and an electro magnet in said circuit adapted .to attract above the platform, a curtain secured at its upper end Within said box, a bar attached to the lower end of the curtain, spring catches for engaging said bar and each procopies of this patent may be obtained for five cents each, by addressing the Commissioner of iate nts, a

subscribed my slgnature vided with an armature, an electric circuit including said contacts, said circuit in position to attract said armatures, said spring-supported portion of the platform When depressed serving as a cir-l cuit closer to close a circuit and energize said magnets.

In testimony whereof, I have hereunto this 29th day of December A. D. 1913. a
